Everyone knows there's only one constant in the technology world, and that's change. This is especially evident in the evolution of Programmable Logic Controllers (PLC) and their varied applications. From their introduction more than 30 years ago, PLCs have become the cornerstone of hundreds of thousands of control systems in a wide range of industries.
Pull-out box Seal it tight. Know consumption and emergency rates. Schedule delivery time. Implement FIFO. Maintain condition of your storage facility. Rotate according to shelf life. Regulate temperature and humidity. Store lubricants indoor. Put a label on it. Shake up stored lubricants. Routinely analyze new oils.
From conveying items in production, to palletizing them on the way to the dock door, manufacturers are searching for automated material handling systems to boost their bottom line. Where speeds are low, depalletizing and palletizing operations can be done manually.
Keeping the line moving at the tool crib has always been a problem. Without an efficient method for handling the congestion of workers waiting for the tools they need, it’s easy for employees to spend more time in that line than the company might like.
Application and operators: These are the two things that should drive the decision of purchasing a lift truck, not acquisition cost. You need to know how well potential trucks are designed for your application. And you need to know how well they’re designed for operator confidence, productivity and safety. With the appropriate truck in the hands of a confident operator, productivity is optimized. And when that machine is built to last, you get the winning combination of high productivity, safety and low total cost of ownership.
Materials management is essential to better supply-chain performance. One way to improve the flow of product all along the supply chain is to use plastic reusable packaging. World-class companies like Ford, John Deere, Harley-Davidson, Tyson and others have already recognized the value of reusable packaging in moving their product faster, better, safer and more cost-effectively. A study conducted by Michigan State University, for example, noted that one U.S. automaker saved $10.9 million a year over a four-year period after a $16.3 million investment in reusable packaging.
For maintenance and plant operations, one device that can often represent significant cost is the sensor, particularly in harsh applications such as chemical and petrochemical processing. Often exposed to or immersed in highly corrosive solutions and subjected to extremely high operating temperatures and other severe conditions, pH sensors are the critical front-line probes that gather and deliver key data.
Investments in infrared thermography will return handsomely when used as part of a well-planned maintenance program. Unfortunately, many companies don't get those returns. In fact, thermography all too often becomes a burdensome expense, and the program is eventually abandoned. One reason this happens is because managers fail to understand the basics of the technology and the needs of their staff who use it.
What do safety, health, productivity and floor-cleaning schedules have in common? All of these aspects of your plant can be improved by making optimal use of modern floor-mat options. And mats available from textile service companies offer customization options and features that surpass those you’re likely to find in a standard industrial catalog.
When compression packing fails, the consequences can be devastating. Packing failure can cause pump damage, pump failure and unscheduled plant shutdowns, not to mention the cleanup effort. Considering the potential cost impact, keeping compression packing functioning properly may well be the most critical factor ensuring that the pump keeps working.
While plant managers and other decision-makers are often surprised with the many developments in loading-dock doors, the selection process need not be challenging or time consuming. Here are five steps to help guide the door selection process, based on the goals of improved safety, increased productivity, lower maintenance costs and overall satisfaction.
Is there any truth to the idea of Web-enabled automation? Is it possible to connect production and processing machinery by their PLCs to the Internet? More relevant, is it practical or profitable? The short answers: First, Internet access can provide compelling competitive advantages for linking manufacturers with service technicians, customers, suppliers and subcontractors.
Whether your company wants to fabricate, modify or repair, investing in a welder and taking a welding course can provide an excellent return on investment. Many businesses have discovered that they can pay for a unit within two days. Additional good news is that you don't have to be a professional welder to achieve good results.
Any strategy to reduce power consumption in industrial systems must include steps that extend equipment performance, reduce heat and minimize friction. One of these steps should be the use of lubricants that enhance machine investment and ensure that critical applications run at peak performance. Today, the challenge to find the right lubricant has been simplified with the advent of synthetics such as polyglycol (PAG)- and polyalphaolefin (PAO)-based products and their additive technology that can be customized for applications and environments.
Each year, industry spends more than $1 billion dollars on task-specific wipers. No longer simply "rags," today's task-specific industrial wipers are available in many sizes, textures and selections specifically suited to maintenance tasks. While a mid-size plant might use 10,000 wipers per year, large facilities might use up to 100,000.
In all process industries, valve failures due to improper, welded valve jacketing occur regularly. Their annual costs in lost production, spare parts and maintenance overtime can run into millions of dollars. How can such losses be avoided? It's simple: Avoid welding jackets for valves. Instead, use bolt-on jacketing to effectively provide thermal maintenance for valves.
Whether the need is to reduce costs or improve yields, increase uptime or improve customer satisfaction, the top priority for any facility manager is always a question of risk. The supply of reliable, clean and cost effective energy is mission-critical, yet this continues to be one of the least carefully managed inputs to a business, and this translates to poorly managed risk.
Roof openings are present in virtually all non-residential buildings. Several types of products can be used to cover them, which serve a variety of purposes. These include providing ventilation or additional light, smoke venting, and/or allowing maintenance workers roof access. Regardless of the openings' function, however, failure to protect workers from the hazards these openings present can have far-reaching consequences.
Air filters are found in many industrial applications, from HVAC and industrial-process air systems to paint-spray booths. Filtration is at the heart of indoor air quality (IAQ), keeping production environments clean and free from the dust and particulates that may reduce product yields. But while filters keep air breathable and processes clean, they only perform when they are maintained correctly.
When the first-shift supervisor for the strut-machining department arrives at his office each day, one of his first tasks is to check e-mail. Not only does he want to see if anyone in his building has sent something important to him, he wants to see if any of the machines in his department require attention.
For years the forklift, powered by an internal combustion (IC) engine has been the workhorse for industrial and commercial material handling of heavy loads. The noise, emissions and performance limitations of conventional forklifts was accepted as a necessary evil. However, one of the most significant trends in the forklift industry is the increased use of electric-powered forklifts.
Automated tank-cleaning systems typically consist of a motorized tank washer, pump and process-control package that make efficient use of resources. Chances are, tank cleaning in your facility is a simple procedure. Workers physically rinse, wash and sanitize them. Or the tanks are rinsed, filled with cleaning solution and water, drained and rinsed again.
There are two basic components to virtually every manufacturing process: motors and the devices that control them. Typically, control devices are large and operate on the same voltage used to power the motors. This results in large motor-control centers that may not provide maximum reliability.
Soy-based engine oil does not readily boil off and resists heat degradation. In tests, it caused a significant drop in hazardous air emissions, compared with petroleum-based oil. The 2002 Farm Bill signed by President Bush encourages the use of biobased products, including those made from soybeans.
Under the Federal Clean Air Act (CAA), many manufacturing operations have become subject to stricter local regulations regarding both VOC (volatile organic compound) and HAP (hazardous air pollutant) emissions. The CAA singles out 188 air pollutants that are of special concern, many of which are used in everyday production and/or manufacturing atmospheres.
